vMETHOD OF AN D APPARATUS FOR DESIGNATING PHOTOGRAPHIC EXPOSURES.

Application led September 12, 1921.

To all whom t may concern.'

Be it known that I, HENRY J. GAISMAN, a

ycitizen of the United States, and resident of upon the sensitizedelement within a camera or other photographic apparatus, by means of atranslu'cid member upon which the desired designation is produced, as bymanually writing thereon, by permitting the light to pass through suchtranslucid member, independently of exposure through the lens for takinga picture, or by exposure through the lens whenv an ordinary exposure ofthe sensitive element is made.

In carrying out my invention I insert a translucid member into a cameraand remove it therefrom without permitting light then to strike into thecamera with such member, and I permit light to strike through thetranslucid member directly from the exterior of the camera withoutregard to the lens, or by shutting off the light from such admission topermit the light to strike through the lens and thence through thetranslucid member, whereby a designation written upon such translucidmember before it is placed within the camera will be caused to bephotographed upon the sensitized element contained in the camera. i

My invention also contemplates improved means for permitting suchtranslucid member to be moved into and withdrawn from the camera withoutengaging the sensitive" surface of the contained sensitized element, andthen to cause sucli translucid member to be held in close contact withsuch sensitive surface to prevent light from striking the sensitivesuiface between lthe latter and said translucid member.

My invention further comprises novel details of improvement andcombinations of parts that will be more fully hereinafter set forth andthen pointed out in the claims.

Reference isto be had'to the accompanying drawings forming part hereof,wherein,

I The camera. or photographic apparatus illustrated in the accompanyingdrawings comprises a frame 1 having covers 2, 3, hinged in a well knownmanner, and adapted to contain a lens 4 connected with the bellows 5secured within the frame, and said camera frame is provided with meansfor i'otatively supporting the spools 6 carrying a sensitized element,such as a. flexible film 7, all of which .parts may be of any well knownconstruction, my improvements hereinafter described being applicable foruse in connection with cameras or photographic apparatus adapted tocontain sensitized elements. such as plates or flexible films havingsensitized surfaces. At 8 is a translucid member, such as a plate or barof glass, Celluloid or other corresponding material, upon whichdesignations may be produced and retained as desired, such as by writingthereon, and through which light may pass, the surface of which materialmay be suitably roughened in anyvwell known manner, to permit Writingthereon, as with a pencil, to retain the marks Written, for; whichpurpose the surface .of member 8 may be roughened as at 8, Fig. l, inthe nature of ground glass. The member 8 is adapted to be placed withinthe camera in front of a portion of the sensitive surface of' thecontained sensitizedelement 7. Photographing `upon the sensitive surfaceof the designatlon written upon member 8, may be accomplished bypermitting the light when required to strike through member 8 from theexterior of the camera or from the lens 4. To such ends I have shown aholder, frame or trough 9 adapted to receive member 8, and shown havingledges 9 upon which said member rests, said holder being open 'on itsupper side or on the side opposed to element 7, the bottom 9b of holder9 and the sides of the holder around member 8 serving to prevent lightfrom striking through member 8 from Within the camera. Bottom 9b ofholder 9 is shown. as removable from the holder. being 'shown supportedby its bent edges 9' to slide in guides 9g of the side arms of theholder(Fig. 12), whereby said bottom may be removed when it is desired topermit light from within the camera to strike through member 8 a ainstthe sensitized surface of element At one end holder 9 is provided with ahollow but entirely covered chamber or compartment 9a communicating withthe adjacent edge 8b of member 8' (Fig. 7) which is adapted to litclosely against the compartment 9a (Figs. 2 and 7). The outer open endof the compartment 9a is shown provided with a shutter 10 pivotallysupported at l1 upon holder 9, and shown provided with the flangedportions 10a to fit over the outer end of compartment 9 to normallyprevent the entrance of light and admit light when required. Holder 9 isslidably supported to be pushed into and pulled out of frame 1, forwhich purpose holder 9 is shown provided at opposite edges with guidinggrooves 9c adapted'to engage spaced guides' 12 suitably supported withinframe 1 (see Fig. 8), and so located'that the outer face of member 8will be close Yto the sensitive surface of element 7. o keep member 8from engaging said surface-When being pushed into'l or pulled out of thecamera, and yet to permit said member to closely engage said sensitivesurface when the designation upon member 8 is to be photographed uponsuch sensitized element, the camera is provided with means to move thesensitive surface into Contact with such member when the latter is inthe desired position within the camera. LIo this end I have shownguiding rollers 13 for element 7 sup'- ported upon spring-like arms 14:secured within the camera frame, and having a normal outward springtendency serving normally to raise the element 7 out of contact withmember 8. The cover 3, when placed in final operating position, isadapted to push element 7 into contact with member 8, and to this enclcover'3 is so located over the exposure portion of lelement 7, betweenthe supporting rollers 13, as to push such portion of element 7 intoengagement with member 8 (see Fig. 8). I have shown a pad 15, which maybe of suitable relatively soft or flexible material, such as felt,secured on the inner face of cover 3 to engage the back of element 7.Cover 3 is shown provided with so flanges 3a adapted to entercorresponding grooves l in the Walls of frame 1 (Figs. 3

and 8), to exclude light from the camera when cover 3 is partly orwholly in place.

To retain cover 3 in close contact with element 7 in the operatingposition, and also to retain said cover closed upon the camera frame butraised so that element 7 may be out of contact with member 8, when thelatter is moved in and out of the camera, I

have shown cover 3 provided with an apertured catch plate 16 (Fig. 3)adapted to engage the several spaced projections 17a of the catch spring17 secured to frame l, a

button 18 carried by frame 1, adapted to engage catch 17, enablingdisengagement o f said catch from plate 16 when required. Thearrangement issuch that cover 3 mayy be raised slightly and retained inysuch position without causing the flanges 3a to pass 100 out of thegrooves 1a While memberl 8is being inserted and removed, and that whenexposure is to be made cover 3 may be pushed inward to cause thesensitive surface of element 7 to engage member 8.

To prevent light from entering the camera with the' member 8 when thelatter is being pushed into the camera, or removed therefrom, I providea shutter 20 (Figs. 2 and 7) shown hlnged at 21 within frame 1, and nor-110 mally pressed by a spring 22 to close opening 23 in frame l, (Fig.7), through which member 8 and its holder 9 are inserted into thecamera. Shutter 20 is preferably provided With a rib 2Oa (Fig. 7) toengage a 115 corresponding groove 24 Within the camera to aid inexcluding light when said shutter is closed. To further exclude lightfrom the camera around opening 23 I provide an extensible pocket, shownas a bellows 25,of 120 suitable flexible material, suitably secured uponthe exterior of frame 1 in front of and around opening 23, and adaptedto receive member 8 and its holder 9, the outer end ot which bellows isprovided with jaws 26 125 shown pivoted together at 27, and adapted toclose in box-like form (Fig. 5) upon the outer portion of compartment 9aot holder 9, which compartment 9a is shown provided with grooved membersor recesses 9 to re- 130 ceive the edges of jaws 26, whereby holder 9 isdetachably connected with the bellows. The arrangement is such that whenplate 8 is placed in holder 9, the latter may be passed through theouter open end of the bellows, and the jaws 26 closed upon the holder 9(shutter 10 having been closed) and then the holder 9 is pushed into thecamera (bellows 25 collapsing) said holder will push shutter aside (Fig.2) and member 8 may thus be pushed into the camera so far as desired infront of the sensitive surface of element 7, cover 3 being at such timeslightly raised. Cover 3 may then be lowered to cause engagement of'said sensitive surface with member 8. Toiprevent i holder 9 from beingpushed into the camera frame when bellows 25 is not pulled outsufficiently far to enable jaws 26 to be closed upon the parts 9 offrame 9, and to prevent shutter 20 from being pushed aside 'by holder 9if the latter is not properly connected with the bellows, I provide astop 28 on holder 9 normally projecting upwardly from said holder (Fig.10) in position to engage the outer wall of the camera, said stop beingshown carried upon a rod 29 journaled in bearings in holder 9 andnormally held by a coil spring 30 with stop 28 projecting upwardly, saidrod having a laterally disposed linger 29a shown located in compartment9a and beneath opening 31 of said compartment, one ofthe jaws 26 havling apin 32 (Fig. 13) adaptedto pass through opening 31 to engage andpress down linger 29 when a jaw 26 is closed, thereby to turn stop 28downwardly in front of frame l and permit holder 9 to be pushed throughopening 23. If attempt should be made to insert holder 9 into the casingwithout causing pin 31 to operate stop 28 as stated, said stop willprevent insertion of holder 9 into the camera, hence bellows 25 must bepulled out the proper distance to cause pin 32 to pass through opening31 to 'operate stop 28, as stated. l

In order to determine accurately the extent to which holder 9 is pushedinto the camera at any desired time, I have shown said holder providedwith a series of spaced openings or recesses 33 along one edge, adaptedto receive clip 34 (Figs. 10, 11 and 12), which clip may be adjustedalong holder 9 to the desired position, so that such clip will engageframe 1 and limit inward movement of holder 9 as desired. The bottomwall of holder 9 may be provided with lines 9d, which may be seenthrough the translucid plate or member 8, as a guide in writing upon thelatter (Figs. 1 and 10). To protect bellows 25 and its attached partswhen not in use, I have shown a housing 35 secured upon the exterior ofthe camera to close over the collapsed bellows. Said housupon thecamera, and a hinged portion 35b having closed sides and ends adapted tofold over the bellows, as shown in Fig. 2, and to be folded outwardly asshown in Fig. 5, to permit operation of the bellows.

Cover 3 is shown provided with a chamber 3c on its outer side adapted tocontain holder 9 and plate 8, when the latter are not to be used, whichchamber is shown provided with a hinged wall 3cl to permit entrance ofholder 9. A spring 3e operating against wall 3'?, as in Fig. 8, retainswall 3d closed.

Instead of having holder 9 closed at the bottom, where it receives thetranslucid member 8. (thereby requiring light to strike through thecompartment 9n when shutter 10 is opened) said holder may be open on thetop and bottom, and on its inner end, as shown in Figs. 14 and 15,whereby light j may strike through member 8 from the lens when the usualexposure is made through the latter for taking a picture.

In accordance with my invention, (using the holder or frame 9 having theclosed sides and bottom with ppen top with the transl'ucid member 8therein), the desired designation such as a name, date, initials, objectphotographed, or the like, is writtenupon member 8, at a suitable partthereof, (as near the edge to be lirst'placed into the camera), theshutter 1() is closed, (the shutter 20 being normally' closed againstopening 23), the jaws 26 are opened, holder 9 with the contained member8 are then inserted in the outer open endvof the bellows, jaws 26 areclosed upon holder 9, stop 28 being thereby lowered, cover 3 is raisedslightly, as indicated ip Fig. 3, and holder 9 and plate 8 are thenpushed inwardl into the camera in front of a desired portion of thesensitive surface of element 7, and cover 3 is then closed tightly tocause the sensitive surface of said element 7 to be pressed againstmember 8. A preferred manner of photographing will be to admit light tothe camera throughi the photographing lens to photograph the objectdesired upon the portion of element 7 that is not obstructed by holder 9in the ordinary manner, and then shutter 10 will be opened and closedallowing the desired time exposure. The light that strikes throughchamber or compartment 9? and through translucid member 8 causes thewriting upon the latter to be photographed upon said sensitized elementwithoutregard to the use of the photographic lens 4. The writing uponmember 8 will thus be photographed upon the sensitive surface yofelement 7, within a mortise or relatively light- Struck portion of saidsensitive surface, whereby the writing will be clearly defined and keptfrom mingling with the picture photographed upon element 7 because ofthe ottom 9a closing holder 9. Such designation photographed uponelement 7 will be adjacent tothe picture photographed thereon.Photographing through lens 4 upon the sensitive surface of element 7(adjacent to the part of such sensitive surface that was exposed to theaction-of the light through member 8 as stated) is prevented by reasonof the opacity of holder' 9 and the fact that` tized element 7. lt willbe understood, however, that, it desired, after member 8 has been placedin position-in front ot the sensitive element 7 as stated, and beforethe'object has been photographed through the lens upon the portion ofthe sentitized element unobstructed by holder` 9 and member 8, theshutter l0 may be opened and closed allowing desired time exposure, tocause photographing the designation upon the portion of element 7 infront of member 8 and holder 9, and then exposure may be made throughthe lens upon the portion of element 7 that is not .obstructed by holder9, and before element 7 is moved. Member 8 may be left in place forphotographing the designation thereon upon any desired consecutivenumber of pictures, or may be removed and replaced as desired, with thesame or different designations produced thereon.

ln Figs. 14 and 15 holder 9 is represented as having its bottom 9bremoved and its inner end open, the holder thus'being in skeleton formbeyond compartment 9a. With member 8 placed in the holder as abovestated, and the holder and member 8 placed in thecamera, the light maystrike through member 8 from the lens l when usual exposure of element 7is made, and without opening shutterlO, whereupon the picture and thedesignation upon member 8 will be simultaneously photographed on .thesensitized element, since the light then will strike from lens 4 notonly directly upon the porf tion of the surface of sensitized element 7exposed to the lens, but through member 8- and the camera then may beusel in the ordinary manner.

'suiicientl low the light to's'trike through the same to ln the presentembodiment of my invention, the face of the translucent tablet 8 iscovered by the bellows 25 which prevents the passage of light throughthe tablet to the interior of the camera during the movement of thetablet frame through the opening in and that he may use the samedesignation, l

suchas a dateplace, name or the like, for any desired consecutivephotographs, or may change such designations by removing member 8 andwriting new designatioins thereon, as frequentlyv as desired.

By causing the designation upon the surface of translucid member 8 to beheld in contact with the sensitive surface of element 7 when the latteris held against member 8, and by preventing the light from strikingthrough member 8 into the interior of the camera, from theopening in theouter end of holder 10, l am enabled to cause such designation to bephotographed upon such sensltive surface when shutter 10 is opened,

because then the light striking through translucid member 8 is, at suchdesignation; prevented from striking the sensitive surface, according tothe density or opacity of such designation, thereby producing a superiorphotograph of the designation upon the sensitive element. lVhe'n,however, the light passes through translucid member 8 from within thecamera, (from the photographie lens) without passing through shutter l0,it is advantageous to have the designation in Contact with the sensitivesurface of element 7 in'order to produce sharper photographic lines uponelement 7 than if the designations were not in contact with thesensitive surface.

It will be understood, that after the sensitized element 7 has beenexposed to the light, to photograph the designation or picture, or both,thereon, said element will be developed in any well known manner forprinting pictures therefrom.

Ihave used the term translucid as meaning a member or plate 8 of any`suitable'inaterial other than opaque, and which will be transparent ortranslucent to alphotograph the designationthereon upon the senstivesurface of element 7.

By the term sensitized element as used .herein l mean any suitableplate, Celluloid,

paper, or other film, commonly employed for photographing, which issensitized photographically or, sensitive to actinic rays of li ht.

glt is, of course, immaterial Whether the apparatus containing myinvention is strictly speaking a camera, that is, whether or not itcontains a lens and shutter as part of the permanent structure, as thedevice is primarily a holder for photographic sensitive material asfilm, and all the operative parts could as Well be embodied in aseparate structure adapted to be applied to any of the Well knowncameras, and, therefore, the term camera as used in the claims is to beunderstood as meaning a device adapted to hold photographic material sothat it may be exposed in the usual way.

lt Will be understood also that when the designations on the translucidmember 8 are intended to be light printed on the film by light admittedthrough the open end of the holder 9, it is essential that the materialof which the member 8 is composed be of such nature that sufficientactinic light Will travel or be transmitted longitudinally of the memberand passl to the film beneath the designations formed on its surface andordinary plate or Window glass is found to be efficient for the purpose.l

The term photographing, when used in the specification and claims todescribe rev cording the designations on the film, is intended to meanlight printing by the uneven passage ofvactinic light onto thesensitized element, due to the masking effect produced by the more orless opaque designations on the translucid member.
